From c6efc48af630e439816ee77a6054feec001b0d0c Mon Sep 17 00:00:00 2001 From: Linus Torvalds Date: Sat, 8 Apr 2023 10:33:54 +0800 Subject: [PATCH] bpf: add missing header file include MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit stable inclusion from stable-v4.19.274 commit c7603df97635954165fb599e64e197efc353979b category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I6TIG1 CVE: NA -------------------------------- commit f3dd0c53370e70c0f9b7e931bbec12916f3bb8cc upstream. Commit 74e19ef0ff80 ("uaccess: Add speculation barrier to copy_from_user()") built fine on x86-64 and arm64, and that's the extent of my local build testing. It turns out those got the include incidentally through other header files ( in particular), but that was not true of other architectures, resulting in build errors kernel/bpf/core.c: In function ‘___bpf_prog_run’: kernel/bpf/core.c:1913:3: error: implicit declaration of function ‘barrier_nospec’ so just make sure to explicitly include the proper header file to make everybody see it.
